How to Create and Use a Redstone Clock in Minecraft

As a Minecraft player and redstone engineer with over 10 years of experience, I will provide a detailed guide on how to create and use redstone clocks in Minecraft.

What is a Redstone Clock

A redstone clock is a redstone circuit that generates regular redstone pulses. The pulses can be fast or slow depending on the type of clock. Clocks are commonly used in builds and redstone contraptions to power or time other components.

Some examples of using a redstone clock:

  • Power a dispenser at regular intervals to act as an automated item shooter
  • Extend or retract pistons repeatedly to move blocks and entities
  • Open and close doors automatically to simulate activity in a base
  • Flash redstone lamps on and off for lighting effects

Types of Redstone Clocks

There are several types of redstone clocks that produce pulses at different speeds. The main types are:

  • Repeater clock – A very fast clock that pulses every 1-2 redstone ticks
  • Hopper clock – Produces slower pulses by moving items between hoppers
  • Comparator clock – Uses comparators and redstone torches for fast, compact clocks
  • Pulse length clock – Produces pulses of longer durations that can be adjusted

Constructing a Basic Repeater Clock

The repeater clock is a simple redstone oscillator that produces a fast clock pulse. Follow these steps to build one:

What You Need

  • 1 Redstone repeater
  • Redstone dust
  • Building space

Step-by-Step Instructions

  1. Place a redstone repeater facing in any direction
  2. Place redstone dust in front of the repeater and to one of its sides
  3. Place a redstone torch on the side of the repeater with the redstone dust
  4. Break the redstone torch

This will create a rapid clock pulse. The repeater delays the signal from the torch enough to create an oscillating circuit.

Using a Hopper Clock

Hopper clocks create slower pulses by transferring items between containers. Follow these steps:

What You Need

  • 2 hoppers
  • 2 comparators
  • Redstone dust
  • Container with items (chest, hopper etc)

Step-by-Step Instructions

  1. Place 2 hoppers facing into each other
  2. Place redstone comparators leading out the sides of hoppers
  3. Connect comparators with redstone dust
  4. Funnel items into one of the hoppers

As items transfer between hoppers, the clock will pulse. Add more items for slower pulses.

Controlling Other Devices with a Clock

Connecting other redstone components to a clock allows them to activate in sequence. For example:

  • Dispensers placed next to a fast repeater clock will rapidly shoot items
  • Doors near a hopper clock will open and close at regular intervals
  • Pistons attached to clocks can push blocks back and forth

To connect other devices, simply place redstone dust between the clock and the component you want to activate.

Advanced Use Cases

With some creativity, redstone clocks can be integrated into complex builds:

  • Randomizers – Use several out-of-sync clocks to power random components
  • Long-range timing – Employ pulse length clocks to send signals long distances
  • Sequential powering – Power components one after the other using offset clocks

By combining different clock speeds and pulse lengths, intricate automated systems can be constructed.


With these designs and examples, you should now understand the purpose of redstone clocks and how to construct the main types. From simple builds to complex contraptions, redstone clocks are useful components for powering and timing other redstone devices. Whether you want to build redstone farms, hidden bases, or decorative builds, put this redstone knowledge to use with some creative clock mechanisms. Let me know if you have any other questions!
